  1. Participation of the Joint Institute for Nuclear Research (Dubna) in PANDA experiment at Future GSI Facility A.G.Olchevski January 2005 Nuclear Structure Physics Physics with Antiprotons Nuclear Matter Physics Plasma Physics Atomic Physics

  2. JINR-GSI Workshop on future GSI facility, 20-21 November 2003,Dubna

  3. Program of JINR-GSI Workshop on future GSI facility PANDA GENERAL CBM

  4. Participation of the Joint Institute for Nuclear Research (Dubna) in the Future GSI Facility JINR interests at GSI: ● Accelerator Physics ● Nuclear Matter ● Physics with Antiprotons ● Applications Possible JINR Contributions: ●Magnets of SIS100 ● CBM Experiment ● PANDA experiment ● New projects (spin-physics, antihydrogen, mesoatoms, etc.)

  5. PANDA Experiment ● Excited glue (glueballs and hybrids) ● Charm in Nuclei, Charmonium ● Hadrons in Matter ● Hypernuclei, etc. Using the ALICE experience the JINR team is capable to design and construct the magnet system (superconducting solenoid and conventional dipole) for PANDA And also make contributions to the PANDA detectors: ●DIRC (Rich detector) ●MDC (Mini Drift Chambers) ●Muon Detector  Straw Detector  Forward RICH

  6. Superconducting Solenoid (2T) and DM with water cooled winding(2 Tm)

  7. Cross-section of the solenoid Cross-section of the dipole magnet

  8. JINR team opportunities and actions • On-site coil winding facilities (solenoid & dipole) are available; • On-site cryogenic facilities to test coils are available; • A number of enterprises contacted in contest of the construction PANDA magnets: MKB “Raduga”, “Energomash”, MKB “Fakel”, NPO “Lavochkin”, NPO “GELIYMASH”; • Management of Russian Ministry of Industry dealing with the conversion of the military industry has contacted to provide government support to build magnets in Russia.

  9. JINR facility for windingof flat pancakes

  10. less space than aerogels costs of calorimeter no problems with field DIRC 10000 PMTs ! Detecting Internally Reflected Č-light (existing at BaBar)

  11. Participation in DIRC • JINR group (in collaboration with KBSU (Nalchik) and FGUP “GRAN”) intends to take part in R&D on MCP – PMT. The R&D will include improvements in MCP PMT manufacturing, development of new photocathode and readout techniques. • New type of photon detectors – Si-MCP, based on photolithographic masking of the channel pattern on the Si surface are on consideration also. These newly emerged Si based MCP could open completely new possibilities in the photon detector technology. • Fused silica/quartz from Russian industry as a base material for DIRC radiators will be tested.

  12. Photon Detectors

  13. Construction of the MDC prototype • flux – up to 105 cm-2 c-1 • magnetic field – 2T·m • spatial resolution 200 m

  14. Proposed design • 2 semi-circular parts, R=900 mm • 6 drift cell layers of the coordinate doublets (XX', UU', VV'). • 3 mm cell width and 3 mm gap between the sensitive wire plane and the cathode. • Protvino, HERMES design

  15. The MDC prototype • One semi-circular plane • 256 signal wires • Test of different variants of electronics • Gas choice

  16. MDC potential frame

  17. Muon Tracker for PANDA • Previous JINR/DLNP Lab experience in technology: DELPHI (CERN/LEP), D0 (FNAL/Tevatron), COMPASS (CERN/SPS) • Muon tracker based on Iarocci tubes' modification: Mini-Drift Tubes (MDTs) • Main purpose: L2/L3 muon trigger/filter with precise muon pattern ID • Total for PANDA: 4 000 MDTs detectors (wires & strips r/o), 32 000 TDCs channels, 25 000 FADCs channels • Estimated cost (joint Dubna/Torino resources): about 1 M Euro, (f/e electronics requires additional evaluation) • MDTs production rate at JINR central workshop - 20-60 detectors/day, so matches reliably PANDA' construction timetable

  18. example event: pp  f f  4K Central Tracking Detectors Straw-Tubes: 15 skewed double-layers

  19. Forward RICH The RICH for PANDA is optimized for the particles identification in the momentum range from 0.6 GeV/c up to 10 GeV/c and an angular range 1°- 22°.

  20. Optical Scheme Forward RICH The design of the forward Ring Image Cherenkov detector with achromatic and short focusing optics has been considered and detailed simulation is performed The proposed RICH scheme is fitted well to the PANDA setup and provides excellent PID features Research of optical materials and the photo-detectors for the RICH is in progress.
